That video is too cute! They're Trixie brand products. I got them on Amazon. You can Google Trixie US for their catalog of products. My cats have all their puzzle toys. Note, the tube flipping one is called Trixie mad scientist on Amazon, if I remember correctly. Everything else should be the same as the catalog. Or, just search Amazon. Keep in mind they make trees too so you'll have to narrow down the search.

re- the video, thanks, yeh it cracks me up the way she does that. She will nose it along the floor sometimes and seems to forget to look to see if any fell out. Not sure she's the brightest cat I've ever had LOL
